High-density liquid-cooled GPU node for blockchain workloads

Task

The client required a configuration for intensive blockchain scenarios: working with nodes, transaction processing, storage and quick access to large volumes of data, as well as tasks that use GPU acceleration.

• High GPU Density
• Large amount of RAM
• The fastest system disk
• Elimination of air cooling in favor of a stable liquid circuit

Solution

The basis of the system was a configuration with five RTX 5090, combined into a single computing array. This approach provides a high level of parallelism and allows you to effectively scale tasks related to data processing and calculations.

To work with large amounts of data, an 8 TB Kingston FURY Renegade G5 SSD (Gen5, up to 14800 MB/s) is installed. It is used as the main high-speed storage layer - for fast operations, indexes and active data. Additionally, two 4 TB SSDs are connected, which the client integrated into the system to expand the total volume. RAM – 512 GB DDR5 6400 MHz. This volume allows you to store large sets of data in RAM, reducing disk load and speeding up operations.

Key element of the project — cooling system. All five GPUs and the processor have been converted to water blocks. The circuit is built using two Bykski B-1080-SPD-CEC-X radiators, which provides sufficient heat dissipation area even when all components are loaded simultaneously. Liquid cooling here is not aesthetics, but a necessity: with such a GPU density, air solutions do not provide stable temperature conditions.

Implementation

The entire system is assembled taking into account the uniform distribution of the thermal load and careful layout of the circuits. Using hoses instead of rigid tubes allows for a more flexible layout and simplifies maintenance without sacrificing reliability. Special attention is paid to cable management and access to components - the system remains maintainable even with high installation density.

Result

• Work stably under constant load
• Efficiently scale GPU tasks
• Quickly process and store large amounts of data
• Maintain temperature stability without throttling

This is not just a powerful assembly, but a tool designed for a specific type of load where continuous operation and predictable performance are important.
